A friend of mine has a CD that documents the development of the Off the Wall album... a lot of the early demos and outtakes. What shocked me was how close some of the Jackson family demos were to the final product. Michael and Janet playing the bottles percussion part on "Don't Stop til You Get Enough', Tito's basslines, that kind of thing.

While Quincy is 'the man', don't discount how talented and creative they all were even before he got involved.
